The growing crowd of smart speakers is ready for your command

Alexa, Google Assistant, Siri and Cortana, oh my! With numerous smart speakers of all shapes, sizes and prices now available, you can find the one that fits your needs best. 

The Amazon Echo popularized the smart speaker when it made its debut in 2014. With Amazon's assistant Alexa built in, a simple voice command allowed you to do so many things -- from playing music to searching the internet to controlling your smart home.

The Echo quickly became a cornerstone of our smart home. Before it, setting up a smart home for multiple users was a nightmare, so having a centrally located assistant that anyone could talk to was a revelation.

Since then, Amazon's worked to make the Echo and Alexa better and better. The current second-generation Echo (pictured) sounds better than before and has an aux-out jack so you can plug it into your own speaker system. Plus, it's only $100. 

But the Echo's not alone anymore. In fact, Amazon itself has a number of Echo alternatives that also have Alexa built in.

In addition to Amazon's options, Google, Apple, Sonos and Microsoft jumped into the game, along with a number of other competitors. Click through to see your smart speaker options.

The first big competitor to the Amazon Echo, Google Home helped debut Google's digital assistant (just called Google Assistant). The $100 Home offered a lot of the same functionality as the Echo, and integrated with Google's services such as Google Calendar and Google Maps. 

Since the Home debuted, Alexa and Google Assistant have engaged in a thrilling back-and-forth as the two main competitors in the smart speaker space continually try to outdo the other. 

Apple's smart speaker is now on the market as well. The $350 Apple HomePod boasts amazing sound along with the smarts we've come to expect from smart speakers, thanks to Apple's digital assistant, Siri. 

The expensive HomePod doesn't have as many capabilities as its competitors from Amazon or Google, and you can stream songs only from Apple Music. Plus, it could leave a stain on your wood furniture -- but if you're invested in Apple anyway, the HomePod's sound quality won't disappoint.

Even before Google Home debuted, Amazon expanded the Echo lineup with the Echo Dot. Now on its third iteration, the Dot is still only $50 and it looks and sounds better than ever. Essentially an Echo with most of the speaker cut off, the Dot offers Alexa's full range of abilities, and it plugs into your own sound system. It was and still is our favorite of the bunch -- the value and versatility of the Dot are unmatched. 

To compete with the Dot, Google expanded its own smart speaker lineup with the $50 Google Home Mini. The Mini offers a more affordable and stylish entry point for Google Assistant-enabled smarts. Disappointingly, you can't plug the Mini into your own speakers, but it still boasts the same tricks as Google Home for less.

If you want a Google smart speaker with high end sound quality, the Max fits the bill for a price. The $300 Max sounds great playing a variety of music genres and still boasts all of the smarts of the original Google Home.

The $150 Amazon Echo Plus sports the same Alexa smarts we've come to expect from Echo devices. The Plus adds a ZigBee radio to the standard Echo formula. ZigBee is a low-frequency signal used by smaller smart home devices such as light bulbs and door sensors, so you can use the Amazon Echo Plus as a hub for your smart home. 

Perhaps the most unique twist on Alexa's abilities, the $100 Echo Look is an Echo with a camera. The cam's not for security; it's for full body selfies and fashion advice -- seriously. And it actually works. Take selfies and compare outfits, and the Look will use algorithms and advice from real stylists to suggest what to wear. 

With Alexa and Google dominating the smart speaker race, Microsoft's Cortana had a steep hill to climb to gain relevance. The $200 Harman Kardon Invoke helps Cortana put up an admirable fight. Cortana doesn't have the same breadth of abilities as its competitors yet, but the Invoke works well and has good sound quality. 

If sound quality is your top priority in a smart speaker, look no further than the $200 Sonos One. The first smart speaker from Sonos makes listening to music a joy, and it has almost all the tricks of an Echo speaker or a Google Home because it has both Alexa and Google Assistant built in. It even works with Apple Airplay 2, making the Sonos One a great option for clever shoppers willing to step away from the first party options. 

The Sonos One is definitely our first choice if you want a third-party smart speaker, but you have plenty of other options as well. The Fabriq Riff works with Alexa, costs the same as a Dot at $50, and has a built-in battery. 

The $100 Fabriq Chorus comes in a variety of color options, and you can take the Alexa-enabled Chorus on the run. 

The MegaBlast on the left and the Blast on the right cost $300 and $230, respectively, but boast serious sound quality in addition to portable Alexa-enabled controls.

The Eufy Genie imitates the Dot, but at an even lower cost. The Alexa-enabled Genie is only $20 and plugs into your speakers with a 3.5mm cable, too. 

One of the first third-party Google speakers to hit the market, the $100 TicHome Mini is also Google's first battery-powered smart speaker. It's even splash-proof. With Google Assistant built-in, the TicHome can do almost everything Google Home can do.

Popular speaker-maker JBL has also brought Google Assistant into a whole new line of speakers. The pictured Link 20 is part of that line. It's also portable and waterproof.
